Love for God is the only sufficient motive for evangelism. Self-love will give way to self-centeredness; love for the lost will fail with those whom we cannot love, and when difficulties seem unsurmountable [sic], only a deep love for God will keep us following his way, declaring his Gospel, when human resources fail. Only our love for God – and, more important, his love for us – will keep us from the dangers which beset us. When the desire for popularity with men, or for success in human terms, tempts us to water down the Gospel, to make it palatable, then only if we love God will we stand fast by his truth and his ways.
– John Cheeseman, as quoted in Mark Dever’s The Gospel & Personal Evangelism, pp. 100-101.
